IPC: H01H51/32
Abstract: 132,021. Drysdale, C. V. Sept. 2, 1918. Alternating-current relays.-An alternating- current relay comprising a pivoted magnetic needle supported in the field of a permanent magnet and within an operating coil is tuned by varying the position of a magnetic shunt adjacent to the poles of the magnet or by varying the position of the needle and coil relatively to the poles of the magnet. Modifications are described for rendering the relay insensitive to mechanical disturbances and to the effects of a uniform external field. The relay may control a moving- coil relay, the movement of which is damped by means of a copper band around the coil. In the arrangement shown in Fig. 1, the operating coil B is fixed between the poles of a permanent magnet A provided with a shunt F, the position of which is varied by a screw F<1>. A magnetic needle D is pivoted within the coil B and carries a contact arm D' adapted to engage lightly fixed contacts E. The movements of the arm D' are limited by means of rubber buffers H. In the modification shown in Fig. 3, the coil B and needle D are mounted upon a bracket. J the position of which, relatively to the poles of the magnet A, is adjusted by means of a graduated member K. The relay controls a moving coil relay L the movements of which are damped by a copper former M, and the contact arm L<1> of the relay L makes tangential sliding contact with a horizontal platinum brush N. In the modification shown in Fig. 5 and 6, the operating coil B is pivoted about the same axis as the needle D and carries two contacts E arranged on each side of the arm D<1>. The movements of the coil B are controlled by springs P so that the periodic time of the coil B is the same as that of the needle D and arm D<1> thereby avoiding contact between the arm D<1> and the contacts E when the relay is subjected to a rotary motion about the axis of the needle D and the coil B. In the modification shown in Fig. 7 and. 8, a needle D carrying an arm D' is pivoted in the field of a magnet A, and a needle D<2> carrying arms D' is pivoted in the field of a magnet A<2>. When the relay is subjected to a mechanical disturbance, the contacts arms D<1>, D<3> do not engage, but upon the energization of a coil B surrounding the needles D, D<2> the contact arms D', D<3> move in opposite directions to engage each other. In the modification shown in Figs. 10 and 11, the relay is rendered insensitive to mechanical disturbances and to the effects of a uniform external magnetic field by placing the needles D, D<2> between the poles of a magnet A. Contact between the arms D<1>, D<3> is effected by placing the needles within two oppositely energized coils B, B<1>.

Title: Improvements in or relating to loading and unloading devices for roll particularly in textile finishing machines, such as calenders or the like
Inventor: HARZENDORF GERHARD
IPC: D06C15/02
Filed: 1958-01-31
Abstract: 873,902. Finishing fabrics. ERSTE MASCHINENFABRIK KARL - MARX - STADT VEB..Jan. 31, 1958, No. 3348/58. Class 42 (1). In a device for varying the load on a roller, for instance in a calendering machine, the loading is effected mechanically and the unloading hydraulically or pneumatically, the loading and unloading mechanisms exerting pressure on the opposite sides respectively of an elastic member such as a compression spring, which transmits pressure to the roller. In the machine shown in Fig. 1, the roller 1 is that which is to be subjected to varying loads, and has its bearings 7 mounted in the machine  frame so as to be movable vertically. Shafts 6 fixed to the bearings 7 each has threaded thereon a compression spring 8 and a bush 5 which is prevented from rotating relative to the shaft by a key 30, and terminates at its lower end in a piston 29 which operates inside a cylinder 15. The bush 5 comprises an external thread for engagement with the internal thread of a worm wheel 4, and when the latter is rotated by means of the worm 3, the bush 5, which is prevented from rotating, moves upwards, thereby compressing the spring 8 and applying pressure to the roller 1. The pressure is relieved by pumping fluid from a tank 11  into the compartment 14 of the cylinder 15, thereby forcing the piston 29 downwards and further compressing the spring 8. The same amount of pressure may then be re-applied to the roller 1 by draining the fluid from the compartment 14 back into the tank 11. In a modification, the worm wheel 4 is situated below the cylinder 15, the latter being vertically movable, in which case the bush 5 is dispensed with and pressure is applied to the spring 8 via the cylinder 15 which is moved upwards by means of a pin screwed into the worm wheel and pressing against the base of the cylinder.

Filed: 1958-04-28
Abstract: 922,805. Cigarette-making machines. D. W. MOLINS, and MOLINS MACHINE CO. Ltd. April 27, 1959 [April 28, 1958], No. 13409/58. Class 130. [Also in Groups XXX and XXXV] In a continuous rod machine where tobacco is supplied through a passage 4, Fig. 1, to a conveyer band 1 to form a filler which has portions of greater density than other portions, to produce dense end cigarettes, the filter is trimmed by a device 9 prior to wrapping. As shown the band 1, Fig. 4, is perforated to hold the filter thereon by suction and the perforations in the band are varied at selected portions 18, 20, Fig. 4, so as to cause the suction to have a different effect at the said positions then at the adjacent parts of the conveyer. More tobacco adheres at the portions 20, which form the denser portions in the wrapped rod. In Fig. 1 the conveyer 1 receives doublelength mouthpieces from a mechanism 13 prior to the supply of tobacco and the resultant composite filter of alternate tobacco and mouthpiece sections is passed through trimming devices 9 on to a cigarette paper web 10 for wrapping. The conveyer 1 of Fig. 4 is modified as shown in Fig. 5 by the addition of a single line of holes 19 at the places where mouthpieces are deposited. To synchronise the conveyer 1, driven by a friction drive 2, with the cut-off mechanism, a light 21 and photoelectric cell 22 are arranged on opposite sides of the conveyer and associated with an apertured wheel 23, Fig. 2, driven from the drive shaft 29 of drive wheel 2, which normally scans the last row of small apertures of a section 18, the light passing through which is insufficient to activate the photo-electric cell 22. If the conveyer becomes retarded so that the aperture in the wheel 23 scans the larger perforations 19, the photoelectric cell is activated to energize a solenoid 33 which activates a pawl mechanism 34 to rotate a worm wheel 40 which adjusts the differential mechanism 39 to advance the wheel 7 and restore the band 1 to its correct position. A similar mechanism may scan the last row of a band of perforations 18 to correct the band if it becomes advanced. Specifications 895,733, 916,141, 922,806 and 922,807 are referred to.
